New member, purchased my first 911 a few weeks. I've started to notice a jerkiness or stutter somewhere in the powertrain when I accelerate hard (80% throttle). So far repeatable in 2nd and 3rd gears between 2,000 rpm and 5,000 rpm. I can't say if it turns up elsewhere as I typically run out of road at that point!

Wanted to see if anyone else has seen or heard of this issue. Car is a 2017, 30k miles and CPO.

I too experienced this with PDK on my 2017 C2S. I found using sport or sport plus minimized this although I went with a manual this time around to completely avoid it.

Turn off auto/off button, the one that cuts off the engine when you are stopped at lights etc.

Thanks both, I'll try both options when I get home this evening. I generally drive the car in Sport which also deactivates the Start/Stop function so I'm guessing that the issue will still present.

I've booked the car into my local OPC to get it checked out but first wanted to make sure this wasn't a "standard feature" before I waste my time at the dealership.

Car diagnosed with a bad coil pack. Part not in stock and no loaner car available so driving around in GF's Wrangler for the next few days.

Damn. Glad you figured it out!
